You very kindly advised me via LinkedIn on SEO companies and how the one I use might be inhibiting my position in Google rather than helping.
Well...
I did all that you suggested, as well as removing everything the SEO company had put on and... BINGO!
I'm now at the top on the front page of Google search under Garden Design or Garden Designer on my three nearest towns.
Once again, thank you SO much for your help.
Best regards,
T.
